Is this Chem II? because I don't know "buffer solution". This problem is in ACS.

Yes this is Chem II. There are 2 version of the ACS exam. One is for first semester (chem I) and the gen chem exam is for chem I and II. Was your course I or II? We did a big long chapter on buffers in chem II.

Yes, its inorganic II. If you bought the ACS review book, it'll contain both inorganic I & II. But you won't see questions like this on the inorganic I exam.
